Synthesis, spectroscopic, electrochemical redox, solvatochromism and anion binding properties of β-tetra- and -octaphenylethynyl substituted<i>meso</i>-tetraphenylporphyrins

Abstract

β-Phenylethynyl (PE) porphyrins exhibited unique photophysical properties and solvatochromic behavior due to ICT from the porphyrin core to PE moieties. Further, Zn(<sc>ii</sc>) porphyrins were utilized for anion sensing.
